Problem after installing test pipes
I just installed top speed resonated test pipes on my 06 6mt coupe. After installing them, my cel light came on (to be expected) but i also get a weird rattling sound while driving. It happens between 2 and 3k rpm and only when im fully off the gas. While its happening, if i press on the gas a little, or if i go into neutral, it goes away. It sounds like a high pitched rattling.
I dont know if this has anything to do with it, but the metal
Brace that bolts to the cats is not in as the top speed pipes didnt have brackets on them.
Any ideas?
Thanks

They must be hitting something. Under load, they probably get shifted to where it has space, until you let off the gas. I'm not sure if this applies to your test pipes, but for ART pipes, it's required to trim down a stud on the driver side heat shield that's very close to the resonator and can cause rattling.

All test pipes with stock exhaust manifolds will create a chatter/hiss/rattle under deceleration. Mine do it as well between 2-3k RPMs.
My guess is that it has something to do with the exhaust flow, and the sudden change in diameter from the exhaust manifolds to the test pipes. The ID of the outlet for the stock manifolds is pretty tiny compared to the test pipes' IDs.
